Well, it ist certainly not 'not correctly identified'. The opposite is true.
It is absolutely correctly identified. It's just that the vendor of
HSODBC ;-) doesn't fully support all ODBC datatypes (especially Unicode wide
character types). You could try to use SQL_ASCII, or another 8-Bit only
codepage to get around this.
